Wind Farm and Wind Turbine Telecommunications Interference Assessments

Wind Turbine and Wind Farm TV, Radio and Telecommunications Interference Assessments

We undertake TV, radio, telecommunications and mobile phone network pre and post-construction signal surveys to assist developers discharge associated planning conditions. We work in England, Wales, Scotland and Ireland to assess the impacts from one single wind turbine to 90+ turbine schemes.

Currently the exact impacts of wind turbine
generated signal interference upon standard definition (SD) and high definition (HD) Freeview television services is not fully quantified, but is understood to be sometimes disruptive. Research is being
undertaken by a number of institutes to accurately quantify any impacts.
Much work is based on theory from the following document – “The Effect of the Scattering of Digital Television Signals from Wind Turbines, Document 6E/467-E (B/DPI 055)“, which is a modification of Recommendation ITU-R BT.805. That work was expanded during research by Aegis for Ofcom, “RF Measurement Assessment of Potential Wind Farm Interference to Fixed Links and Scanning Telemetry Devices, April 2009“.

Ofcom commissioned the study (conducted by AEGIS Spectrum
Engineering / ERA Technology) to examine wind turbines and the
potential for RF interference. In the study, it was determined that
wind turbines do degrade radio link performance and while further study is
required, the trials have established useful methods for investigating
and characterising the impact of turbines on radio systems and wireless networks. Whilst the report focused on fixed point-to-point wireless
links, not terrestrial television broadcast networks, some of
the principles behind the causes of interference are similar. The work is
summated in the following Ofcom document from pages 58 to 66.

It is an important consideration for wind energy developers to understand the potential effects and impacts of a project upon the reception of broadcast television / radio for local residents. We can assess these impacts and provide guidance on the possible magnitude and cost implications of any potential impacts. We can also coordinate local effort to restore the reception of television services should this be required as a result of unforeseen or predicted interference.
